Configure struts-config.xml, validator-rules.xml and validation.xml in struts

Core java OOPs Tutorial

Core Java Interview Materials

In this chapter, We will discuss the configure struts-config.xml, validator-rules.xml and validation.xml in struts application.The core configuration file for the Struts framework is by default struts-config.xml for Struts.

 The web.xml file is the standard servlet configuration file. You need it because every struts application is also a servlet application. You will need to add some basic config to the web.xml file to use Struts to process your requests.
The struts-config.xml is the main configuration file for Struts. Its where all the struts Actions are defined and what JSP pages are used to display them.
